net: Add GSO to vlan_features initialization
Just add GSO to vlan_features initialization, and update comments.
When we set offload features, vlan_dev_fix_features() will do more check.
In vlan_dev_fix_features(), final features is decided by
features of real device and vlan_features of real device.
